The Energy Charter Treaty provides a multilateral framework for energy cooperation that is unique under international law. It is designed to promote energy security through the operation of more open and competitive energy markets, while respecting the principles of sustainable development and sovereignty over energy resources.
The Energy Charter Treaty was signed in December 1994 and entered into legal force in April 1998. Currently there are fifty-three Signatories and Contracting Parties to the Treaty. This includes both the European Union and Euratom.
